The end result went racing last weekend, 2nd round of our Jap street class competition...
guess what I won class!!! no breakages!! beat three Skylines with circa 700-900 in the eliminations.
In the final match up with my old friend in his 700bhp Rx7, my reaction time and launch was the deciding factor even though he reeled me in towards the end with his huge power, his terminal of 146 to my 131mph, both hit 10.8 for the quarter.
I didnt do any burnouts all weekend so my 60fts were only in the 1.5ft to 1.6ft range, but I felt the clutch was not as snappy off the line, felt there was a progression of power being fed in.

Next round I will be lowering tyre pressures,doing a burnout and upping the boost, and see if anything breaks, it seems for now the valve is doing its job.
Here is the vid of the final

Thants awesome! COngrats!!

Wich "orafice" did you use?

I was gonna do the tube nuts, but I have about a mile less clutch line LOL. I went with the -3 banjo, 2 sections of 10" -3 line, and the female metric adapter. will be finishing the install tonight. But it tucks right under the master cylinder, and ill be selling my goodridge SS clutch line soon

 

I used the middle sized one the .28 I think it was.
When undoing the valve to change the pill, be warned you need to put that thing in a vice, and use a breaker bar\torque wrench to undo the thing, its been done up to 50lbs of torque and needs to be retorqued to the same value so you dont get leaks

 

Yea, i put in the middle pill 2 and was blown away how torqued it was lol

 

Congrats! Ya I used a vice too then it wasn't too hard.

The proper way to do it.
Let's see who figures it out first!

 

Here's my first guess...

It's a meter out flow control, the valve is under $10? They use them in lifts.

 

if thats only $10 and it works, what didnt you tell me earlier I could have saved some money Crispeed hahaha

 

I bought the tilton flow control valve just like you.

 

send on the specs chris!!

 

That one specifically looks like the unit from Magnus, flow control combined with line lock so it only limits off the line. Its not $10 either

 

yep magnus launch controll device

Launch Control Device
Everybody who has been racing long enough knows that dropping the clutch is a sure way to be picking up a whole lot of parts at the starting line, not to mention makes you inconsistent as a drag racer.

This Device was developed by 9sec9 and we decided to give it a shot in our race car. It worked well! What it did was take away alot of the thinking we had to do to make sure we were slipping the clutch. we adjust it to where we wanted for the track conditions for that day, and we forget its there. Just let go of the clutch and go. This will provide the amount of slip you have dialed into your hydraulic clutch system.

The built in Line lock restricts on launch, then bypasses when off the 2 step button. Must use a mighty vac to bleed correctly.


$275.00



looks like it could even be set up for push button launches

 

looks impressive! one question how does the line lock work? I am assuming it goes into the clutch line not the brake line, so hows does it lock your front brakes ?

 

That design have been used by the drag bike cummunity for many years.
Actually tested that exact valve way before it was being marketed and sold by Marco(Magnus Motorsports). What we found in testing is that by replacing the actual adjustable valve with the tilton flow control gave way better results. Then for ultimate control you can use tthe ecu or a switch to activate the solenoid the way you want. Using the TFCV by itself without the solenoid affect the clutch engagement in every instead of just first gear.

 

It's not actually a line lock it uses a solenoid exactly like a line lock to limit the clutch line flow on launch only, and then afterward just bypasses the orifice through the solenoid.

 

fot those that still dont follow, the black thing with a silver **** is the adjustable flow valve, the line lock solonid when activated closes forcing the fluid to take the path through the valve, then when you release the solenoid, the fluid flows through the "line lock" solenoid unrestricted.

A blast from the past!

Did you find best results with using the tfc/solenoid for just 1st gear? I wonder if it may also be usefull for the 1-2shift , to allow speed shifting, using the 1/2 switch as a controll?

 

Changed a few things but it seems to work and very cheap to make. Used a Zex nitrous jet to control fluid back pressure. The "T"s are from the junk yard and the line lock is the cheapest Jegs sales. So far so good. No leaks and seems to work as planned. Have the momentary button on the steering wheel. Also got that from the junk yard. It's a kill switch for aftermarket alarms.
Just thought I would share.

 

Where exactly did you put the nitrous jet?

 

anyone tried this version?

clutchmaster fcv?

 

Here is another version, under $10 and works just as great, no bleeding, adjustment with a flathead or phillips, you can't beat it

 

HAHA is that one of those gas struts that hold the hood open?

 

Its flow control baby!!! But yes, it can be used on screen doors as well... lol

 

lmao. Win!!
